7 '0 all whom it may concern:

Be it known that I, JOHN l'llNES, subject of the King of (ireat Britain, residing at 289 Finchlcy road, London N.\V., England, engineer, have invented certain new and useful Improvements in Means for Making or Repairing Roads and like Surfaces, of which the following is a specification.

This invention comprises improvements in the means for making, repairing, or iniproving roads and like surfaces. In the renting or flush carpeting of roads with ituminous or other binding material to form a hard bound durable waterproof road, work can only be satisfactorily earried out in fine dry warm weather, as'the stone or other road making or dressing material must not only be quite free from moisture to insure good results but also desirably heated to a given temperature,-

and as under normal conditions such material, after once being wet, takes a long time before it is rid of moisture, long delays occur. entailing loss through cost of labor, etc. It has been proposed with the object of avoidin these delays to dry and heat portions 0 road surface by forcing heated air on to the same beneath a hood so as to prepare for the making or repairing operations.

The benefit of this method has not been obtained owing to the known apparatus necessitating uncovering the heated and dried road surface for the making or repairing operations, and in this heated and dried state cold air and moisture present in the atmosphere are at once absorbed and the desired penetration of the binding material and filler is not obtained.

The object of my invention is to provide apparatus, embodying a suitable furnace or heater, and means for forcing or drawing air through same to a hood, with means for heating the binding materials and discharging the same on to the road surface within the hood or immediately behind same, so that the absorbent properties of the heated anddried surface during cooling areutilized to effect the penetration of the grouting of binding materials. Thus the added material marries with the existing road.

The penetration of these materials is increased if they are discharged under pressure on to the road surface which is preferred.

Accordingly a portable apparatus is employed and the air heater or furnace is ar' ranged with its outlet pipe or trunk passing through or alongside a container or containers for the bituminous or other binding material and preferably a container forthe sand or other filling material, so as to heat the same as the hot air or gas forming a hot blast passes along the trunk to a hood or hoods directed over the road or like surface. The heated bituminous material is led to sprayer pipes or nozzles beneath the hood and is forced into the heated and dried road surface within the hood. The sand or filler is preferably discharged into the trunk leading to the hood and a valve or deflecting plate is provided for shutting ofl or deflect ing the hot air or gas from the hood into a sand receptacle upon the hood to blow the sand or other filler within the hood into the road surface with the sprayed binding material. The blowing in of the sand or other filler by the current of hot airor gas is not an essential feature of the invention. as the filler may be distributed many other way as by gravity. It is desirable that the current of hot air or gas should be cut off from thehood when the blinding material is being distributed to avoid any risk of setting fire to the atomized or finely divided material.

On the drawings Figure 1 is an elevation of a portable apparatus with my invention applied.

Fig. 2 is a plan thereof.

Fig. 3 is a rear end view of Fig. 1.

Fig. 4 is a longitudinal section of the apparatus shown at Fig. 1 omitting the front part of the chassis carrying the engine, blower, and associated mechanism.

Fig. 5 is a section of the hood.

These drawings show one example ()f-COT1- struetion in which I mount upon any suit able running frame a, a blower b, a suitable driving engine 0, and. a furnace or air heater The running frame may be adapted for tank 6 and preferably along between that tank and a bin g for sand or like other finely divided filling material. The air or gas trunk f passes along, to the rear end of the tank 6 where-an outlet pipe 71. is prosquare pyramidal form an the main enters at the vertex and preferably deflectors are arranged Within the entrance to distribute the heated air or gas equally within the hood.

A by passage is for the air or gases may be arranged leading around the tank with dampers k in the main f so that the whole or part only of the gases may be sent around the tank. Any other arran ement of fines for circulating heat around t e tank may be followed but preferably means will be provided in any case for insurin all the heat passing along the main trun f when desired to the hood so asto insure sufiicient for dthe purpose of drying and heatingthe roa An important feature of the apparatus is the rovision for spraying or distributing the indin agent tar, bitumen, asphalt, or other suita le binder,'within the hood together with a heated filler such as sand,

chippings, clinker-dust, Portland cement, and the like, so that the binder and the filler are delivered or forced, preferabl the latter, into the road surface within the ood which is within the zone of heat or imme- 80 diatel .behind same. For this. purpose a pipe rom the tank e leads to a spraying or distributing pipe I which may, if desired, be provided with spraying nozzles of any suitable construction.- A pressure pump m 86 may be em 10 ed to force air above the bitumen, asp at, tar, or any other binder within the tank 6 to force the heated liquid to the sprayers to insure its atomization or fine division and to facilitate its penetra- 4 0 tion into the road. .-Any other means of forcing the li uid may be employed.

For the er feeding screws such as n Fig. 4 or any other conveying means, may be employed in the bin 9 and the filler'may be discharged into the outlet )5. and in the illustrated arrangement it enters a receptacle 0 on the hood 7' and is blown by the heated air or gas through the slot ;0 into the hood near the liquid dis 'rge. 60 A deflecting valve 9 is shown for-closing the normal entrance to the hood so as to deflect the filler and the current of heated air or gas into the receptacle 0 see Fi 5. The screws n in the sand bin 9 may e driven I from the road wheelsor by hand or power as desired. The bottom of the race tacle 0 down which the sand, etc.,;will fal in its discharge 'may be curved transversely or provided with radiating ridges or grooves or any-like means forfacilitating' even distribution of finely divided materials may be employed. A deflector 0? may be emplo ed so that the filler maybe discharged wit in or outside the hood as desired.

5 "It is preferableto provide a old air inlet the hood is of to the heated air of the trunk f for example as at 1' so that cold air maybe admitted for regulating the temperature of the binder and filler, or if .desired' a b pass direct from the fan or blower, suitab y controlled, I

may be employed but this is not claimed 61' 86. It is desirable to rovide fiues or inings so that the heated air or gases may be utilized when desired entirely for heating the binding agent and the filler for ex am 1e when the machine is not at work.

eyond the hood a second sprayer pipe 8 Fig. 2 may be earned by an extension t so that a second coat of the binder may be given to a treated surface as the hood is drawn forward for further operation.

It will be understood that the invention is not limited to the above construction which is given as an example only.
